This is not an AIBU but we received our new statement and they have put us on a much higher tariff - 15p kw instead of our usual 9p. This is a 60 percent increase from May.
Dh phoned to complain and they stated they had to ask our permission to put us on a lower tariff. Does that make sense, yes if you work for N power.
So please check your statements and complain .
